The double-layer stretch film unit is suitable for producing low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE) plastic wrap film. The machine adopts twin screws, and the two feed hoppers use different formulas for the raw materials. The film produced can achieve the effect of sticking on one side. It is widely used for packaging of building materials and hardware accessories.
1. The screw and barrel are made of 38CrMoAlA alloy steel, which is made by nitriding treatment and precision processing
2. The cooling device adopts circulating water to cool, and the cooling effect is good, so that the transparency of the film is good.
